Double Worm Gearing
The exclusive use of the involute helicoid thread form on the worm and gear provides for high efficiencies and lengthy service lifestyle. The hardened, ground and polished alloy metal worm develops a even, work hardened surface area on the bronze gear. For this reason, the worm gears put on in and improve with prolonged service while various other gears are deteriorating.

ouble Reduction Worm Gearbox
Ever-Power Double Decrease Worm Gearboxes are two stage worm reduction units.
A specially designed primary worm decrease unit is integrally mounted on a standard single reduction Ever-Power worm gearbox which forms the next stage. The composite systems provide the most 
compact and rigid set up for large reduced amount of speed necessary for sluggish shifting machinery. A wide range of ratios up to 4900:1 is offered.
Double Reduction Worm Gear Package Sizes Available with us are 40, 50, 60, 75, 85, 100, 125, 150, 175, 200, 250, 300, 350, 430.
Nominal Gear Ratios: 100:1, 150:1, 200:1,300:1, 400:1, 600:1, 750:1, 1000:1, 1200:1, 2000:1, 2800:1
Nominal ratios listed are a typical selection of commonly utilized ratios from the overall range of Ever-Power Dual Reduction Worm Gear Box. Details of other ratios on request.

The worm shafts are made of high quality case hardening steel, accurately generated, ground and super finished. The worm tires include phosphor bronze centrifugally cast rims of significant sections welded to rigid centers. Considerable flexibility of shaft layout is permissible with all sorts of Double Reduction products. The dimension drawing for each series shows the various shaft handing plans and the appropriate reference should be quoted when purchasing.
Our standard 700 Series – the heart of Ever-Power rate reducer product line – has been serving industry reliably for over 40 years. Its confirmed modular design has set the industry standard for overall performance and may be the most imitated product in today's worm gear acceleration reducer market. But why settle for a knock-off when you can have the initial – from Ever-Power.

Product Features
The 700 Series' large oil reservoir provides efficient heat dissipation and lubrication for longer operating existence.
Its multi-position mounting versatility permits installation in virtually any position.
Housings are straddle-milled, top and bottom level, for precise alignment of horizontal and vertical bases.
Internal baffles assure positive, leak-free venting.
The 700 Series' rugged casing, fabricated of fine-grained, gear-quality cast iron, provides maximum strength for optimum durability, in addition to greater precision during worm and gear alignment.
Ever-Power's 700 Series high-strength bronze worm gear is straddle mounted between heavy-duty tapered roller bearings to improve thrust and overhung load capacities, sizes 713-760.
Our 700 Series' high-strength steel output shaft assures capacity for high torque and overhung loads.
Pipe plugs allow easy fill, level, and drain in any mounting position.
The 700 Series' super-finished oil-seal diameters on both input and output shafts extend seal existence.
Both 2D and 3D CAD drawings are available in our eCatalog.
DOUBLE REDUCTION GEAR
Ever-Power Double Reduction Worm Gear Devices are constructed using two one reduction worm gear models. The primary worm gear device is specially designed to attach integrally on a standard single worm gear device which forms the secondary stage. The complete gear unit becomes small and rigid in set up for slow shifting machinery. A wide range of ratio from 75:1 to 4900:1 is available. These equipment units are particularly suitable for high torque slow-velocity drives. Worm gearing conforms to BS-721.
